Porsche 968 - Engine Oil Level Check; Oil Level Checking Procedure; Oil-Level Warning System

Engine Oil Level
The oil level should be between the two marks
on the dipstick . To get a true reading the car
s hould be on level ground.
Checking Oil Level
You s hould not check the oil level immediately
after turning off the engine - the circulating oil
takes a few minutes to return to the oil sump.
1. Pull out dipstick and wipe it clean with a
clean rag.
t Push dipstick all the way back in, pull out and
read off oil level. The difference between the
"max." and "m in ." marks is about 1.5 litres.
If the oil level has reached the bottom mark, al -
ways top up with oil until it reaches the max .
mark.
Oil-Level Warning System
The float of the oil-level warning system
measures the level of the engine oil in the sump .
When the engine is started and the oil level is
too low, the words ENGINE OIL in the left
instrument cluster light up, together with the
central warning lamp.
A correct reading will not be obtained unless the
car is standing level.
Method of Operation:
The oil level is measured with the ignition on be-
fore the engine starts. The warning lamps light
up at the same time to indicate correct oper-
ation.
When the engine starts the warning lamp goes
out if the oil level is correct. A repeat-measure-
ment inhibitor means that no further measure-
ment can be made · for some 1.5 to 2 minutes.
If the warning lamp fails to go out once the en-
gine starts, the engine-oil level has dropped near
the min . mark on the dipstick. In this case, stop
the engine and switch off the ignition.
The first measurement indicating "oil level too
low" is stored in the control unit, which means
that the warning lamp will not go out even if the
engine is started several times in succession.
After waiting for approx . 2 minutes (to allow the
oil to drain back into the sump), check the oil
level at the dipstick and top up to the max.
mark . The warning lamp will go out once the
engine is started.
If the warning lamp remains lit even after the oil
level has been topped up, seek the assistance
of an Official Porsche Centre.
